Description

  The present invention relates to a beam connecting panel, a column reinforcing bar connecting panel, and a reinforcing bar structure.

Reinforced concrete (RC: Reinforced-Concrete) reinforced structures are used relatively often as structures in the civil engineering / architecture field such as bridges and buildings. In recent years, the height of reinforcing steel structures has also been increasing. Reinforcing bars used for reinforcing concrete are arranged through various processes such as cutting, bending, and welding long reinforcing bars in the field.

  Reinforcing bars for two-way beams at the beam-to-column joint of a reinforced concrete column and the beam are, for example, through bars in which the reinforcing bars of one beam overlap the reinforcing bars of the other beam Etc. However, in the case of through bar arrangement, the height of the reinforcing bar in the cross section of each beam is different, and the covering dimension from the concrete surface of the beam to the reinforcing bar is different. For example, when reinforcing bars with a diameter of about 40 mm are stacked, it is necessary to increase the thickness of concrete for columns and beams by about 40 mm, increasing the weight and materials of the reinforcing bar structure, and reducing the space in the reinforcing bar structure. Invite. Thus, various proposals have been made to suppress the covering dimension (for example, see Patent Document 1).

JP-A-5-340103

  With respect to the portion where the reinforcing bars intersect, for example, if one or both reinforcing bars are bent so that the reinforcing bars do not interfere with each other at the intersecting portion, the covering dimensions of the reinforcing bars of the beams and columns can be suppressed. However, the work of bending a reinforcing bar requires labor and advanced techniques, and when using a relatively thick reinforcing bar, it is difficult to bend it on site. In addition, the column beam connection part of the column that joins the beam is a part that is subjected to a particularly large load compared to other parts. When the diameter of the reinforcing bar becomes thin due to plastic deformation, the reinforcing bar is pulled out of the concrete and the reinforcing bar structure There is a risk of causing deformation of the entire object. In other words, the beam-to-column joints of reinforced concrete columns that are connected to the beam are structurally important. Especially in recent years, with the increase in the number of reinforced structures, advanced quality control is required. The shortage is also a concern, and there is a need for higher performance of reinforced concrete columns and beam-to-column joints to be joined to beams and to simplify rebar construction.

In this case, the reinforcing bar of one reinforced concrete beam connected to the beam connecting portion is arranged on the same plane as the reinforcing bar of the other reinforced concrete beam. Therefore, the covering dimension of the reinforcing bar of the reinforced concrete beam can be suppressed. In addition, since it is only necessary to connect the reinforcing bars of the reinforced concrete beam to the beam connecting part provided at the edge of the beam panel part, the performance of the reinforced concrete column and the beam-to-column joint to be joined to the reinforced concrete beam is improved and the reinforcement work is simplified. It can be compatible.

  Further, the present invention is a beam connection panel, comprising a beam panel portion disposed horizontally at an upper portion and / or a lower portion of a column beam joint portion of a reinforced concrete column to be joined to a steel beam, and an edge of the beam panel portion. A beam connecting portion formed so as to protrude toward the side, and a steel link connecting portion connected to the steel beam may be formed integrally with the beam connecting portion. .

Hereinafter, embodiments of the present invention will be described. The embodiment described below is one aspect of the present invention and does not limit the technical scope of the present invention.

<Beam connection panel>
FIG. 1 is a perspective view showing an example of a beam connection panel. The beam connection panel 1 is a member used for a beam-to-column joint 102S of a reinforced concrete column to be joined to a beam. The column beam joint 102S is a part of a reinforced concrete column, and is a portion corresponding to the space between the upper surface and the lower surface of the beam to be joined to the reinforced concrete column. For example, as shown in FIG. 1, the columns in which the beam connection panel 1 is embedded are arranged so as to surround a large number of column reinforcing bars 102 standing in a rectangular shape in a top view and the column reinforcing bars 102 standing in the forest. This is a reinforced concrete column that is reinforced with hoop reinforcement. The reinforced concrete column includes, for example, a large number of beam reinforcing bars 101 as shown in FIG. It can be used to join steel beams.

  FIG. 2 is a view showing an example of the beam connection panel 1. The beam connection panel 1 includes a beam panel portion 2 that is horizontally disposed above and / or below the column beam joint portion 102S. The beam connection panel 1 is formed so as to protrude from the edge of the beam panel portion 2 to the side, and the steel beam is connected via a beam reinforcing bar 101 of a reinforced concrete beam or a steel frame connecting member described later. A beam connecting portion 3 is provided. The beam connection panel 1 is preferably manufactured by casting, but may be manufactured using other various techniques.

  Such a beam connection panel 1 is, for example, as shown in FIG. 1, an upper part of a column-beam joint 102S of a reinforced concrete column reinforced by a large number of column reinforcing bars 102 standing in a rectangular shape in a top view and / or When arranged horizontally in the lower part, the beam panel portion 2 is surrounded by the column reinforcement 102 of the reinforced concrete column. The beam connecting portion 3 passes through all or part of the gaps of the column reinforcing bars 102 from the edges of the sides of the beam panel portion 2 to the side, and is a beam reinforcing rod 101 of a reinforced concrete beam, or a steel frame connecting described later. The to-be-connected part which protrudes from a member will be in the state connected.

  For example, as shown in FIG. 2, the beam panel portion 2 is formed in a lattice shape in which rod-like extending portions 4 extending along the longitudinal direction of the beam connecting portion 3 are arranged vertically and horizontally. Since the extension part 4 is located on the extension line of the beam reinforcement 101 connected via the beam connection part 3 provided at the end, a load in the pulling direction from the beam is applied to the beam panel part 2. Also, a tensile load acts along the longitudinal direction of the extending portion 4. In addition, the edge part of the extension part 4 is made into the sleeve which can insert the to-be-connected part which protrudes from the beam reinforcement 101 of a reinforced concrete beam and the steel frame connection member mentioned later, and is fixed with a grout material. The beam panel portion 2 is not limited to the lattice-like form in which the rod-like extending portions 4 are arranged vertically and horizontally as described above. For example, a plate-like member is appropriately provided with a hollow hole or the like. There may be.

  Moreover, the beam panel part 2 is provided with a hose insertion hole 5 having a size capable of inserting a hose when filling concrete. The hose insertion hole 5 facilitates placement of concrete below the beam connection panel 1. In addition, when forming the beam panel part 2 in the grid | lattice form which arranged the rod-shaped extension part 4 in length and breadth, since many clearance gaps will arise between each extension part 4, even if the hose penetration hole 5 is abbreviate | omitted It is possible to flow concrete from the upper side of the beam connection panel 1. In the present embodiment, the hose insertion hole 5 is formed so as to divide a part of the rod-like extension part 4 arranged in the vertical and horizontal directions to form the beam panel portion 2 in a lattice shape. The formed part is provided with a bar-shaped reinforcing portion 6 that is disposed obliquely with respect to each extending portion 4 that is disposed vertically and horizontally. The reinforcing portion 6 reinforces the extending portion 4 divided by the hose insertion hole 5.

The reinforcing portion 6 is disposed obliquely from the end portion of the extending portion 4 divided by the hose insertion hole 5 toward a direction of 45 ° obliquely with respect to the longitudinal direction of the extending portion 4. It is connected to the end of the existing part 4. FIG. 3 is an example of a top view of the beam connection panel 1. For example, the reinforcing portion 6 indicated by the symbol H in FIG. 3 is inclined 45 ° from the end portion E1T of the extending portion 4 indicated by the symbol E1 with respect to the longitudinal direction of the extending portion 4 indicated by the symbol E1. It arrange | positions diagonally and is connected with the edge part E2T of the other extension part 4 which the code | symbol E2 shows. The reinforcing portion 6 thus formed reinforces the extending portion 4 divided by the hose insertion hole 5 and gives the beam connecting panel 1 strength and rigidity that can withstand the load transmitted from the beam reinforcing bar 101.

  FIG. 4 is a view showing an example of a method of using the beam connection panel 1. When joining a reinforced concrete column and a beam using the beam connection panel 1 described above, the beam connection panel 1 is moved by a crane or the like and lifted on the column reinforcement 102 (FIG. 4A). Then, the beam connecting panel 1 is gradually lowered while adjusting the position so that each beam connecting portion 3 protruding from each side of the beam panel portion 2 enters the gap between the column reinforcing bars 102, and the column reinforcing bar The beam connection panel 1 is fixed at an appropriate position 102. For example, the beam connection panel 1 may be bound to the column reinforcing bar 102 with a binding wire, or may be welded to the column reinforcing bar 102 by welding. The beam connection panel 1 is attached to a portion corresponding to the beam reinforcing bar 101 connected to the upper and lower portions of the beam-column joint 102S (FIG. 4B). Next, the beam reinforcing bar 101 is coupled to the beam coupling portion 3 of the beam connection panel 1 (FIG. 4C). When all the beam reinforcing bars 101 are connected to the beam connecting portion 3 of the beam connection panel 1, the bar arrangement work of the column-beam connecting portion 102S of the reinforced concrete column to be connected to the reinforced concrete beam is completed (FIG. 4D). After the bar arrangement work is completed, a formwork is prepared and concrete is poured into the formwork to complete the rebar structure.

  In the case of the beam connecting panel 1 described above, the beam connecting portion 3 to which the beam reinforcing bar 101 is connected is formed at the edge of the beam panel portion 2 that is a plate-like member. The reinforcing bars 101 are arranged on the same plane as the beam reinforcing bars 101 of other beams. Therefore, by setting the core of the beam reinforcing bar 101 of each beam to be on the same plane, the beam height can be reduced and the covering dimension of the beam reinforcing bar 101 can be suppressed.

  In addition, instead of the portion where the beam reinforcing bars 101 cross each other, the beam panel portion 2 is used. The beam reinforcing bar 101 is simply connected to the beam connecting portion 3 provided at the edge of the beam panel portion 2. Well, it is not necessary to place a bar in a part surrounded by the column reinforcement 102 in the column beam joint 102S of the reinforced concrete column to be joined to the reinforced concrete beam. Therefore, it is possible to achieve both high performance of the beam-column joint 102S and simplification of rebar construction. Even if a tensile force is applied to the beam connecting panel 1 due to an earthquake, the beam connecting panel 1 as a whole resists the tensile force, so that the beam connecting panel 1 is difficult to come out of the concrete of the reinforced concrete column. For this reason, the intensity | strength of the whole reinforcing bar structure can be increased, and it also becomes possible to implement | achieve the reinforcing bar structure with a high restoring force.

  In addition, in FIG. 4, although the usage method of the beam connection panel 1 when a reinforced concrete beam spreads from a reinforced concrete pillar to all sides is illustrated, the beam connection panel 1 is not limited to such a usage method. The beam connection panel 1 may be used, for example, for the column beam joint 102S in which the reinforced concrete beam extends from the reinforced concrete column in one direction or two directions. In this case, the beam connecting panel 1 may be provided with the beam connecting portions 3 on all four sides of the beam panel portion 2, or the beam connecting portions 3 where the reinforced concrete beams are not joined may be omitted. Good.

<Steel connection member>
FIG. 5 is a view showing an example of a steel frame connecting member that enables a steel beam to be connected to the beam connection panel 1. The steel frame connecting member 7 is a member that can be used when the steel beam is connected to the reinforced concrete column using the beam connecting panel 1 described above, and protrudes laterally from the edge of the plate-like member to which the steel beam is connected. There are a plurality of rod-like connected portions 9 that are connected. Moreover, it has a plurality of holes through which bolts for connecting the steel beam and the steel connecting member 7 are inserted. Each connected portion 9 is formed at a position corresponding to the beam connecting portion 3 of the beam connecting panel 1.

  FIG. 6 is a view showing an example of a method of using the steel frame connecting member 7. When the steel beam 103 is connected to the reinforced concrete column 104 using the beam connection panel 1 described above, the steel connection member 7 is connected to the beam connection panel 1 after the beam connection panel 1 is fixed to the column reinforcement 102 (FIG. 6 ( A)). Next, a formwork is prepared and concrete is poured into the formwork to complete the reinforced concrete column 104 (FIG. 6B). Next, the steel beam 103 is connected to the steel connecting member 7 protruding sideways from the column surface of the reinforced concrete column 104 (FIG. 6C). If the steel connecting member 7 is used, the steel beam 103 can be joined to the reinforced concrete column 104 with a bolt or the like, so that it is possible to easily join the reinforced concrete column 104 and the steel beam 103 without requiring work such as welding. is there.

  In FIG. 6, after the steel connecting member 7 is connected to the beam connecting panel 1, a mold is prepared and concrete is poured into the mold to complete the reinforced concrete column 104, and then the steel beam 103 is connected to the steel connecting member. However, the steel beam 103 may be connected to the steel connection member 7 first after connecting the steel connection member 7 to the beam connection panel 1. In FIG. 6, an H-shaped steel beam is shown as the steel beam 103. However, the steel beam connected to the steel connecting member 7 is not limited to the H-shaped steel beam. Various steel beams may be connected.

<Modification of beam connection panel>
FIG. 7 is a view showing a modified example of the beam connecting panel 1 described above. The beam connection panel 1 ′ according to this modification is a member that can be used when the steel beam 103 is joined to the reinforced concrete column 104, and is similar to the beam panel portion 2 and the beam coupling portion 3 of the beam connection panel 1 described above. The beam panel part 2 'and the beam connection part 3' which take the form of are provided. In addition, the beam connection panel 1 ′ is formed integrally with the beam connection portion 3 ′ with a steel frame connection portion 8 that has the same form as the steel frame connection member 7 described above. That is, it can be said that the beam connection panel 1 ′ according to this modification is an integrally formed product of the beam connection panel 1 and the steel frame connection member 7 connected to the beam connection panel 1 described above.

  When the beam connection panel 1 ′ according to the present modification is used, the concrete is placed in a state where the beam connection panel 1 ′ according to the modification is fixed to an appropriate position of the column reinforcement 102, and then the column of the reinforced concrete column 104 is used. If the steel beam 103 is connected to the steel connection part 8 projecting on the surface with a bolt or the like, the steel beam 103 can be joined to the reinforced concrete column 104. Even when the beam connection panel 1 ′ according to this modification is used, the steel beam 103 is connected to the reinforced concrete column 104 with a bolt or the like, similarly to the case where the steel beam 103 is connected to the beam connection panel 1 via the steel connection member 7. Since they can be joined, it is possible to easily join the reinforced concrete column 104 and the steel beam 103 without requiring work such as welding.

When adopting a structure in which reinforcing bars arranged in a shape are embedded in concrete, the four column panel sections 13 used for the reinforced concrete columns are each composed of six column reinforcing sections 11 with hoop reinforcing sections 12, as shown in FIG. The structure is connected in a lattice pattern. 9 so that one end of the hoop bar 12 extending left and right so as to be substantially orthogonal to the six column bars 11 parallel to each other can be fastened to the adjacent column panel 13. As shown by reference numeral A, the hole extends further to the side than the columnar portion 11 and forms a hole. And in the part which the hoop bar | burr part 12 of the adjacent column panel part 13 contact | abuts, the end of the hoop bar | burr part 12 further extended to the side rather than the column reinforcement 11 shown to the code | symbol A of FIG. A rod-like engagement portion 12S that engages with the hole formed in the above is provided.

The number of the column reinforcement part 11 with which the column reinforcement connecting panel 10 is provided is appropriately determined according to the number of column reinforcements 102U and 102B of the reinforced concrete column to be applied. Further, the column reinforcing bar connection panel 10 is not limited to an aspect in which four column panel parts 13 including the same number of column reinforcing bar parts 11 are used in combination. For example, when the column reinforcing bar connection panel 10 is applied to a reinforced concrete column having a structure in which column reinforcing bars 102U and 102B are embedded in concrete in a rectangular shape in a top view, the four column panel portions 13 to be combined have different numbers of column reinforcing portions 11 from each other. There is a case to prepare.
